| 英文摘要 | Local heat transfer is predicted in turbulent axisymmetric jets, impinging onto a flat plate. A non-linear k-ε model is used[1], in which both the constitutive law for the turbulent stresses and the transport equation for the turbulent dissipation rate ε have an important contribution in the improved heat transfer predictions. The shape of the Nusselt number profiles, expressing dimensionless heat transfer, as well as the stagnation point value, are well predicted for different distances between the nozzle exit and the plate. Accurate flow field predictions are the basis for good heat transfer predictions. For a fixed Reynolds number, the influence of the nozzle-plate distance is well captured. For a fixed distance, the influence of the Reynolds number is correctly reproduced. Comparisons are made to a low-Reynolds standard k-ε model[2] and the v2-f model[3]. A thorough discussion is found in [4]. Only a summary of those results is discussed here, while some new results are also presented. |
